' 615 L KELAND, FLORIDA VEGETABLE AND ORCHARD HEATER My presentinvention contemplates the provision of a cha "coal burn ig heater forher. ing orchards and use in pro l y to vegetables, the said heater beiu.cted on the principle that the fuel ignitedat the top of the fuel inthe heater, and as the combustion goes down principally around the edgeof the fuel the coinbr ion in a com paratively short time will re. 2rate, a n d the combustion will contii r7 "111d point until the chargeof fuel consumed. floward the end of the operation the lov twelveinches, approximately, of the heat becomes red hot and above that pointvery little heat is generated so that during the latt r consumption ofthe charge the upper par of the heater turns black and cornbu hove theapex of the grate prac ically This action is due to the fact that immerUely after the char e is initially ignited carbon dioxide is generated,and as it is pram" impossible for combustion to take pie ide therelative a and air remain an V erated. The volume of our son dioxidebecomes greater as on. on continues down tl1C-l1921.t61,llill uni l isupplied by the apertures in the co i .r ate so coinbus ion can continueand the 0. charge be consumed. Incident to the oper on of the heater thetemperature is greater two feet out from the heater 1 t the bottom thanit is directly over the top of the heater.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofcons ruction, l in the combination and arrangement of i .i as will behereinafter more fully described and claimed.

In the drawings Figure 1 is a perspective of the heater embodying thefeatures of the invention.

Figure 2 is a vertical sectional view there through.

Figure 3 is a transverse horizontal section taken substantially on theline 33 of Figure 2,

Figure l is a similar view showing the grate removed, and

forms an important part of the invention.

Referringto the drawings in detail, it will be seen that the numeral 5denotes a cylindrical body disposed vertically and supported by legs 6depending from the lower end there of. The lower portion. of the body 5is swaged inwardly at 7 and 8 respectively for forming shoulders and theportion between these shoulders is provided with openingsl) which formbreathers for oxygen.

A strengthening swaged formed shoulder 10 is provided adjacent the topof the body 5.

A. lid 11 is formed with aflange 12 to telescope outside the upper endof the body.

Apertures 12a, are provided in the upper portion of the body 5, and thesaid flange 12 is apertured at 12?). lvlanifestly by turning the lid 11about its axis the oxygen for supporting combustion can be nicelycontrolled.

At 14 is the cone-shaped grate which offers a baflie to draft and afforda support for charcoal. In the preferred embodiment of my invention thesaid grate 14 is provided with a plurality of annular series of openings15 the diameter of the openings in the series being graduated to becomesmaller as the openings approach the apex of the cone.

In the operation of the heater the fuel is i 'nited at the top of theheater and the fuel is consumed in the manner hereinbefore explicitlyset forth. Incident to the operation and as demonstrated by experiencethe temperature is greater at substantially two feet outwardly from theheater at the bottom than it is directly over the top of the heater,this being due to the construction of the grate as described. From thisit follows that the heater will afford a low heat calculated to protectvegetables adjacent to the heater; also, that the heater will dry groundsurrounding the heater for a considerable distance which makes theheater peculiarly advantageous where winter vegetables are raised.

It is thought that the construction, utility and advantages of thisinvention will now be quite apparent without any more detail descriptionthereof. It will be seen that by burning charcoal on the grate, saidgrate will tend to maintain itself clean because of the arrangement ofthe openings 15 and the notches 16, said notchesallowing the sifting outof burnt charcoal.

The structure may be manufactured at a low cost, and made light anddurable so as to be thoroughly efficient and reliable in use in orchardsand other desired places.

The present embodiment of the invention has been disclosed inconsiderable detail merely for the purpose of exemplification since inactual practice it attains the features of advantage enumerated asdesirable in the statement of invention and the description. g

It will be apparent that changes in the details of construction, and inthe combina tion and arrangement of parts may be resorted to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is The hereindescribed heater for burning charcoal, comprising a hollow upright body,and a grate therein supported only at its lower edge and extendingthroughout the transverse area of the hollow uprightbody, said bodyadapted at its upper portion for the passage of gases and open at itsportion, below the grate, for the passage of air; said grate being inthe form of a thin wall which interiorly and exteriorly describes anupwardly extending cone, and being provided in its edge with spaced,comparatively large openings which extend inwardly from said edge, andbeing also provided throughout the remainder of its area with outerapertures smaller than said edge openings and inner apertures smallerthan said outer apertures.
